About

I’m a systems and networking engineer at F5, working on cloud-native and DPU-based networking systems for Kubernetes environments. My work spans datapath, control plane, and routing layers, with an emphasis on building reliable and performant systems. Recently, I’ve been working on: • Datacenter networking protocols (BGP-EVPN, BGP Unnumbered, MPLS, BFD) • RFC-driven development of protocol servers, like for Neighbor Discovery. And also integrating it with real routing stacks (OcNOS, FRR). • Designing and building logging infrastructure, including dynamic log-level updates at runtime. • Root-causing and fixing complex, system-level bugs and release-blocking failures. I enjoy digging into messy systems and understanding why they fail and fixing them. Co-inventor on a few pending patents in the networking / distributed systems space. Open-source enthusiast, with contributions to the SODA Foundation.

Dec 2025 – Present · 6 mos · Hybrid

Worked on BIG-IP Next for Kubernetes, aligned with NVIDIA’s Cloud Partner Reference Architecture for accelerated, cloud-native networking.
Implemented MPLS datapath integration, enabling label generation, propagation and forwarding of labeled routes across networking components, using BGP VPN for VRF based overlay and BGP-LU for underlay.
Implemented BGP Unnumbered support using link-local addressing by designing an RFC-compliant Neighbor Discovery Daemon (NDD) and integrating datapath-side ND/RA/RS processing with routing control planes.
Fully owned a dynamic logging initiative enabling runtime log-level changes without restarts, including inotify-based configuration propagation.
Resolved complex bugs related to BFD for BGP (including unnumbered).
Validated changes through comprehensive unit, functional, and end-to-end testing across datapath and control-plane components.
Co-inventor on a few pending patents in the networking and distributed systems space.

Software Engineer I

Promoted

Jul 2024 – Dec 2025 · 1 yr 5 mos · Hybrid

Worked on cloud-native and DPU-accelerated networking systems across multiple BIG-IP Next releases.
Engineered core datapath functionality for Kubernetes-based egress traffic management, including flow handling, forwarding logic, and security-sensitive datapath behavior.
Implemented datapath-side support for BGP EVPN to enable datacenter networking use cases.
Enabled large-cluster scaling for Kubernetes networking workloads, supporting clusters with more than 32 datapath instances.
Worked extensively on Kubernetes networking integrations, including controller-side logic and Multus-based CNI workflows.
Automated deployment of Scalable Functions (SF) CNI using Multus, including an upstream open-source contribution.
Enhanced control-plane systems through custom resource handling, dependency management, and deployment updates using Helm and operator workflows.
Proactively unblocked cross-team, BVT-critical issues to ensure release timelines were met
Fixed a long-standing datapath restart delay by identifying lifecycle and UNIX signal-handling gaps and introducing a lightweight init-based solution (reducing restart time from ~34s to ~3s).
Improved logging reliability by integrating Fluent Bit/Fluentd and post-failure analysis by investigating core dumps.
Designed and standardized a common C logging framework adopted across multiple C codebases.
Validated changes through layered testing, including unit tests, component-level and end-to-end functional testing, and targeted manual validation.
Collaborated closely with teammates to debug complex system interactions and share operational knowledge.
